Abstract

We performed a clinico-pathological study on cases with early gallbladder carcinoma to elucidate its morphological characteristics.<BR> Thirty cases (33 lesions) were included, invasion was confined to the mucosa in 24 of these cases and involvement of both the mucosa and muscularis propria was seen in 6 cases.<BR> The results are as follows :<BR> 1) In all cases with Ip-type cancer, the depth of invasion was limited to the mucosa.<BR> 2) In Is cases in which the tumor had a broad base, 10mm in size or less, the depth of invasion was up to the muscularis propria.<BR> 3) In cases with IIa-type carcinoma in which the base was less than 15mm in size, no involvement of the subserosa was observed.<BR> In conclusion, it is suggested that with lesions diagnosed by imaging modalities as Ip-type cancers, broad-based tumors with a base of 10mm or less, or IIa-like lesions with a base less than 15mm, there is a high probability that the depth of invasion is limited to the mucosa or up to the muscularis propria.
